Distance-Time Graph Analysis

The video tutorial explains how to interpret and analyze distance-time graphs. It covers the basics of reading the axes, understanding stationary points, and calculating average speed. The tutorial uses examples of Gianna's journey to work and a bicycle journey to illustrate these concepts. It also introduces a useful triangle method for calculating speed, distance, and time.

What is the main difference between a distance-time graph and a speed-time graph?

• Speed-time graph shows distance on the x-axis.

• Speed-time graph shows time on the y-axis.

• Distance-time graph shows speed on the y-axis.

• Distance-time graph shows distance on the y-axis.

What does a horizontal line on a distance-time graph indicate?

• The object is decelerating.

• The object is stationary.

• The object is accelerating.

• The object is moving at a constant speed.

How far did Gianna travel to work according to the graph?

• 18 kilometers

• 15 kilometers

• 17.5 kilometers

• 20 kilometers

At what time did Gianna stop moving during her journey?

• 7:00 AM

• 7:10 AM

• 7:20 AM

• 7:30 AM

How do you calculate average speed using a distance-time graph?

• Divide distance by time.

• Multiply distance by time.

• Divide time by distance.

• Add distance and time.

What is the average speed of Gianna's journey to work?

• 8.75 km/h

• 8.5 km/h

• 9.5 km/h

• 9 km/h

In the bicycle journey, which section represents the fastest speed?

• Section A

• Section D

• Section B

• Section C

What does a steep line on a distance-time graph indicate?

• The object is stationary.

• The object is moving fast.

• The object is moving slowly.

• The object is moving at a constant speed.

How do you convert minutes into hours for speed calculations?

• Subtract 60

• Add 60

• Divide by 60

• Multiply by 60

How far does the bicycle travel in 15 minutes at a speed of 20 km/h?

• 10 kilometers

• 7 kilometers

• 5 kilometers

• 3 kilometers
